Abstract
This paper describes a 3.125 Gbps 4-channel parallel optical transmitter and a receiver module with MT-RJ receptacle designed for a very short reach OC-192 interface between a DWDM transponder and a core router. The discussion is addressed on the following key features: (1) 4-channel 1310 nm FP-LDs with their anodes and cathodes separated channel-by-channel, (2) 4-channel passive optical alignment technology, (3) inter-channel crosstalk reduction technology in a Si optical bench, (4) low power consumption high speed LD driver and receiver LSIs. The applicability of newly developed 3.125 Gbps/ch 4-channel parallel optical transmitter and receiver module to very short reach application has also been demonstrated through a transmission experiment over a 500 m length of GI-50 MMF (graded-index multi mode fiber).
